Passengers aboard two Mumbai-bound Jet Airways flights witnessed a mid-air scare on Friday when one of them breached the safety distance set by the aviation safety regulator.

The incident took place at around 1.30pm and involved a two city-bound Jet flights ferrying passengers from Delhi and Indore, according to the Mumbai air traffic control (ATC) office’s report submitted to the Directorate General of Civil Aviation (DGCA).

The report stated that one the flights strayed from its assigned altitude, which resulted in the safety breach. “Going by the preliminary findings, the flights were separated by seven nautical miles before the cockpit crew corrected the altitude,” said a senior ATC official requesting anonymity. According to the rules, the flights should have maintained a distance of at least 10 nautical miles.

Officials added the pilots corrected the altitude after receiving an alert from the Traffic Collision Avoidance System (TCAS), an in-built safety device that warns pilots about the presence of another aircraft in close proximity.

The TCAS issues two kinds of warnings — traffic advisory and resolution advisory — the first indicates a plane at a vertical distance of 35 to 40 seconds, while the latter is issued when two mid-air planes are separated by 25 to 30 seconds.

“We are yet to ascertain the nature of the emergency in this case. The airline has been asked to submit a report,” said a senior DGCA official.

The official added that the breach took place at an altitude of 30,000 feet when both the flights were preparing to start their descent.

The Jet Airways spokesperson did not respond to HT’s query.
